Oh ho! I think I saw a clue in some of your posts above!
Please check this sequence:
1. Once the machine is running, when you reboot, do you do the Ctl-Alt-Del type reboot? That is, you do not power-off?
2. If you reboot doing a power-off, do you switch back on again with about 10 secs?
3. Do either or both these reboot sequences mean the PC reboots OK without the "wait syndrome"?
IF SO, you MAY have a failing hard drive. The HD is one of the components that fails most frequently in PCs. One of the first signs they are on the way out is that they fail to load properly or promptly on start from cold. Sometimes it may take a few minutes for them to warm up and then go online. Older HDs are especially prone to this. However, it also means they are close to total collapse anyway, with little hope of economic repair.
I take it you do know how to listen for the symptoms? Are you able to try a different HD temporarily?
